Lignosulfonate adsorption on and stabilization of lead zirconate titanate in aqueous suspension

Physicochemical Properties of Calcium Lignosulfonate with Different Molecular Weights as Dispersant in Aqueous Suspension

“…[2,3] Purified lignosulfonates have been widespread practically applied as dispersants of concrete, dyestuff and coal-water slurry dispersants, agricultural chemicals and other industrial binders because of its dispersive, stabilizing, binding and complexing properties. [4][5][6] One of the most important applications of LS is as dispersants, which can prevent the clumping and settling of undissolved particles in suspensions. By attaching to the particle surface, it keeps the particle from being attracting to other particles and reduces the amount of water needed to disperse the particles effectively.…”

Effect of straight-chain alcohols on the physicochemical properties of calcium lignosulfonate

“…4. The adsorption isotherms of CL under various conditions follow Langmuir types [16,22]. The adsorption ability of CL in aqueous solutions is small.…”

“…The formation of LS/cation complexes alters the surface and interface properties of LS, and this property can be utilized to prepare stable crude oil emulsions. Ratinac et al [13] have investigated the adsorption of LS on zirconate titanate powder in aqueous suspensions at different pH. Their results show that the amount of LS adsorbed onto zirconate titanate powder decreases with the increasing pH.…”

The adsorption and dispersing mechanisms of sodium lignosulfonate on Al2O3 particles in aqueous solution

“…In less favorable cases, however, the dispersing stability of suspension is thermodynamically unstable, and flocculation and delamination occur. Poly(acrylic acid) and its derivatives are common dispersants, but LSs are known to be useful for dispersion of kaolin (Le Bell et al 1976 ), lead zirconate titanate (Ratinac et al 2004 ), montmorillonite, and alumina (Palmqvist et al 2006 ). Ratinac et al (2004) evaluated the LS adsorption and stabilization of lead zirconate titanate in aqueous suspension.…”

Ratinac et al (2004) evaluated the LS adsorption and stabilization of lead zirconate titanate in aqueous suspension. A significant component of the overall driving force of adsorption at all pHs was found to be a specific (i.e., nonelectrostatic) bonding, and the authors interpreted the results as an electrosteric mechanism of the suspension due to the expanded shape of the adsorbed molecules at high pH.…”
